For those of you with a 4s on Verizon and staying in the United States. If you are having signal problems where it goes from 3G to the circle off and on then here is a tip that worked for me. 1) Turn your phone off, 2) Eject the SIM Tray, 3) Remove SIM from Tray, 4) Put back SIM Tray, 5) Turn iPhone back on and "Viola!". You then have a clear and smooth signal. This will definitely help with battery life.
